We don't clean a lot of blue stone but do occasionally. We soft wash it with about 45% SH and rinse and it usually come really clean. Over the weekend we attempted to soft wash some blue stone but it just did not come clean. The attached images are the stone after soft washing. The owner informed us someone else uses a pressure washer and it does the trick. I want to try a surface cleaner on it however I was told some time ago not to use a surface cleaner because it will leaves swirls on blue stone. Recommendations?
